Overheating system

Thu, 15 Mar 2001 18:47:51 -0700

I have a somewhat poor suggestion as well.  I am sure others may know more, 
but my husband builds computers and these new cpu's run terribly hot.  If 
your manufacturer material says 45C is too hot and higher is worse, than I 
would tend to agree but that seems to be conflict with what happens in the 
real world.  The only solution we have found is to keep your system below 
55C.  Mine is a 500 I think and it runs about that all the time.

One way is to get the higher fans that mount on the cpu and lot's of cool 
air on the outside.  If it's in a armoire, try putting in a fan that pulls 
heat from the inside of the box to the outside.  There was one that Fry's 
sells that has two extendable blue fans but it's not real fast rpms.  One 
pulls out and one blows in.

If that doesn't work, take your cover off and try to have a fan blow on the 
outside of the case to create a "blow through" and hit the side of the 
armoire to push the air out of the armoire.  I had to place my box next to 
the window which cooled it about 5 degrees lower than it was.  The 
manufacturers that my husband have talked to said that they things all run 
very hot.  They don't use anything but the highest rpm fans.  And most of 
them are sluggish and slow running.

If anyone finds a better fix, I would love to try it too.
